In i.MX8M Mini/Nano SoC the DSI Phy requires a MIPI DPHY bit to reset in order to activate the PHY and that can be done via upstream i.MX8M blk-ctrl driver. So, mark the phy get as optional. v7, v6, v5, v4, v3, v2: * none v1: * new patch Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- drivers/gpu/drm/bridge/samsung-dsim.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
